I recently bought a used Freedom 2500 combi inverter. I tested it by powering a new microwave and it clicked whilst it turned on and off the microwave's clock, but refused to do anything else. Then I connected a 1/2 hp bench grinder and it worked fine with no clicking. Then I connected the microwave as well and it worked both units for a short time and quit. The reason it quit then, was the low battery circuit shut it down.
Why would the inverter not power the microwave on its own? Any ideas. Thanks.

Peter, many microwaves and most electric digital clocks do not like the modified sinewave from some inverters. My microwave will generally work on my Heart inverter if there is another small load connected and operating. Sometimes just turning on the toaster for a few seconds is all it takes to get the microwave started, and then you can turn the toaster off. I can never get my microwave to operate if the temperature in the coach is below 60 degrees (f). Have to use a hair dryer to warm up the control panel.

The clicking noise you hear is the inverter in idle mode. Waiting for a load. My guess is that the micro is not drawing enough to trigger the threshold and wake the inverter up. You can lower the idle threshold or do as Richard suggested and add another load to trigger the inverter to wake up. However, the micro's electronics still may not be happy with the inverted modified waveform.
I found out day before yesterday my dual voltage TV/VCR combo unit doesn't like the modwave from my Heart either. Plays TV just fine, but throw a tape in and it plays as if the tracking is off and the soundtrack is out out of sync. My solution to that will be run it on 12v instead.
Computer is happy as a clam on the modwave. (due to being converted to DC insdie the PC anyway) So far very happy with the Heart. Only suprise is a bit more buzzing noise and dirty power than I expected. Will be running the bus sound system on 12v, I think, to get around the hum issue.

Thanks Guys,
that explains it all.
Shame I only bought the inverter to power things like the microwave and VCR, go figure....... LOL.

I think one of the best things about an inverter such as the Heart is the superb charging capability.

This "combo" unit will independantly charge 2 battery banks and with the optional "link" incorporate the vehicle alternator into the 3 stage 130 amp charging circuit.
It also powers at 50 or 60 cycles, so I am told and some of the combis invert at 120 and 240 volts too.

I have the Heart Freedom Combi 3000 watt inverter. I just installed it last weekend and it seems to work fine. However, please explain the part about independently charging two batteries and using the alternator to 3 stage charge. As far as I can tell, I need to purchase a "Pathmaker" (about $200) to charge 2 banks and I need to purchase an "InCharge" to get 3 stage charging from the alternator. Also, I would need to modify the alternator from internally regulated "N" to externally regulated "P". If there is an easier (read that cheaper) way, let me know. |

Arthur,
I haven't installed mine yet and am only going by what the instructions told me. To involve the alternator I think you need the "link" which is an optional extra. The "link" is a different version of the remote panel as far as I remember. I would get out all the info and check but as we were not going to be using it for sometime, it has been put away in storage.
Just call Heart and they will tell you what you need to know.
